Marcia (left) and Millie Biggs, both 11, say people are shocked to learn that they’re fraternal twins. Marcia looks more like their mother, who’s English born, and Millie looks more like their father, who’s of Jamaican descent.

These Twins Will Make You Rethink Race

Marcia and Millie Biggs say they’ve never been subjected to racism—just curiosity and surprise that twins could have such different skin colors.

When Amanda Wanklin and Michael Biggs fell in love, they “didn’t give a toss” about the challenges they might face as a biracial couple, Amanda says. “What was more important was what we wanted together.”

They settled down in Birmingham, England, eager to start a family. On July 3, 2006, Amanda gave birth to fraternal twin girls, and the ecstatic parents gave their daughters intertwined names: One would be Millie Marcia Madge Biggs, the other Marcia Millie Madge Biggs.

These Twins Are Happy with Their Different Skin Colors. Can’t We All Be?

Though Millie and Marcia are just 11, they understand racism—and the best way to combat it.

From a young age the girls had similar features but very different color schemes. Marcia had light brown hair and fair skin like her English-born mother. Millie had black hair and brown skin like her father, who’s of Jamaican descent. “We never worried about it; we just accepted it,” Michael says.

“When they were first born,” Amanda recalls, “I would be pushing them in the pram, and people would look at me and then look at my one daughter and then look at my other daughter. And then I’d get asked the question: ‘Are they twins?’”

“Yes.”

“‘But one’s white and one’s black.’”

“Yes. It’s genes.”

People who commented on the girls weren’t openly hostile or judgmental—just very curious, Amanda says. And then “as time went on, people just saw the beauty in them.”

Amanda, who works as a home-care aide, calls Millie and Marcia her “one in a million” miracle. But it’s not that rare that a biracial couple would have fraternal twins who each look more like one parent than the other, says statistical geneticist Alicia Martin.

Fraternal twins account for about one in 100 births. When a biracial couple has fraternal twins, the traits that emerge in each child depend on numerous variables, including “where the parents’ ancestors are from and complex pigment genetics,” says Martin, a postdoctoral research fellow at the Broad Institute in Cambridge, Massachusetts.

And research on skin color is further complicated by a history of “study biases that mean we know more about what makes lighter skin light than what makes darker skin dark,” she says.

In genetic terms, skin color “is not a binary trait” with only two possibilities, Martin notes. “It’s a quantitative trait, and everyone has some gradient on this spectrum.”

Historically, when humans have drawn lines of identity—separating Us from Them—they’ve often relied on skin color as a proxy for race. But the 21st-century understanding of human genetics tells us that the whole idea of race is a human invention.

Modern science confirms “that the visible differences between peoples are accidents of history”—the result of mutations, migrations, natural selection, the isolation of some populations, and interbreeding among others, writes science journalist Elizabeth Kolbert. They are not racial differences because the very concept of race—to quote DNA-sequencing pioneer Craig Venter—“has no genetic or scientific basis.”

And yet 50 years after the assassination of Rev. Martin Luther King, Jr., racial identity has reemerged as a fundamental dividing line in our world.

We’re devoting the April issue of National Geographic to the complicated issue of race.

This month’s issue is just a starting point. We’re doing stories on the evolving identities of key ethnic, religious, and racial groups throughout 2018.

They Think We’re Just Best Friends

The twins, for their part, understand quite clearly what racism is. “Racism is where somebody judges you by your color and not by your actual self,” Millie says. Marcia describes racism as “a negative thing, because it can hurt people’s feelings.”

Michael, who owns an auto-repair business, says he’s faced hostility at times because of the color of his skin. He vividly recalls an episode from his youth when a car full of men sped by and shouted slurs at him and his brothers.

“But it’s a different time now,” Michael says. Neither he nor Amanda has ever witnessed racist behavior toward the girls. And both Millie and Marcia say that they’ve never sensed racism when people note the contrast in their looks.

“When people see us, they think that we’re just best friends,” Marcia says. “When they learn that we’re twins, they’re kind of shocked because one’s black and one’s white.”

But when the twins are asked about their differences, they mention something else entirely. “Millie likes things that are girlie. She likes pink and all of that,” Marcia says. “I don’t like the color pink; I’m a tomboy. People are made how they are.”
